Hi Duncan,
I'm with Tom, don't want to be redundant but here's some extra info.
This made me think that the problem is not a 'theshold'. Any thoughts.
Also, if the "bad" number strings are entered at the R command prompt, they
are parsed correctly as the expected number. (not factors)
thanks,

this works
0x1.ffadp-1
> df = read.csv("bad1.csv", header=F)
> str(df)
'data.frame': 1 obs. of 1 variable:
$ V1: num 0.999
but this doesn't
0x1.ffa000000000dp-1
> df = read.csv("bad1.csv", header=F)
> str(df)
'data.frame': 1 obs. of 1 variable:
$ V1: Factor w/ 1 level "0x1.ffa000000000dp-1 ": 1
this also works, which is one less trailing zero.
0x1.ffa00000000dp-1
> df = read.csv("bad1.csv", header=F)
> str(df)
'data.frame': 1 obs. of 1 variable:
$ V1: num 0.999
